Designed for use with Kombat UK small and medium MOLLE assault packs, this 2.5 litre water bladder inserts into hydration bladder compartment and you can channel the drinking tube along the shoulder strap. Kombat UK's Aqua bladder insert has two mounting points on the top of the bladder so it can be hung inside your pack (specifically designed for the Kombat UK pack, but will fit any brands bladder compartment that has this dual point of attachment and can accommodate a 2.5 litre bladder.) Easy to clean with the large screw cap access to the bladder bag and removable drinking tube with bite valve.
